CompletePBX 5 IP PBX vs. Humach vs. Yeastar P-Series PBX System Comparison Chart

Pros

• Easy to use and lots of integrations available like zoom, zoho, Microsoft, Salesforce and so many with latest version
• Easy and quick setup, even for small businesses without a dedicated IT team. Intuitive web-based interface that simplifies day-to-day management. All-in-one unified communications (calls, chat, video) in a single platform. Excellent value for money compared to other PBX solutions. Reliable system with stable performance and good call quality. Flexible deployment options (on-premise, cloud, or hybrid). Scalable solution that can grow with the company. Good compatibility with a wide range of SIP providers and IP phones. Linkus UC app enables efficient remote work and mobility. Responsive and helpful customer support. Strong security features (encryption, secure access).
• The breadth of features - most of which are unlocked with the system license. Others do require a separate license but it is nice to be able to set up a basic system for a customer and if they come back in 6 months and say "we want to implement queues" for example, it is very simple to just configure and turn them on
• Simple to configure, App for iOS and Android work as expected, SSO with Google, Microsoft and Red Hat
• Easy to use, user friendly UI, frequent new features, reactiveness of the team to both client challenges as well as feature requests
• The Yeastar P-Series PBX System is a very complete and well-designed solution for businesses of all sizes. The interface is modern, intuitive, and easy to use, even for administrators without deep telephony expertise. Setting up extensions, queues, and IVRs is straightforward and well documented. I especially appreciate the wide range of integrations available (CRM systems, Microsoft Teams, etc.), as well as advanced features such as video calling, mobility (mobile and web apps), and multi-site management. Call quality is excellent, and the overall system stability is very reliable. Security features and regular updates are also a strong advantage.
• Easy to set up and configure Reliable call quality and stable performance Supports SIP trunks and multiple users Flexible call routing, queues, and voicemail features Scalable for growing teams Cost-effective compared to some enterprise systems
• The system is very reliable and offers a wide range of features for both small and growing businesses. The interface is clean and fairly easy to navigate once familiar, and the flexibility for integrations and customisation is a big advantage. Call handling, routing, and overall performance have been consistently solid, making it a dependable choice for daily operations.
• Wide choice of features Wide choice of compatible handsets Ease of use Straight forward pricing model Excellent support
• True Channel Partnership: Unlike competitors (like 3CX), Yeastar is 100% partner-focused. No direct sales to your leads and no "snatching" customers from your portal. Unified Ecosystem (YCM): The Yeastar Central Management platform is a lifesaver. Being able to provision, update, and troubleshoot multiple client PBXs (Cloud or On-Prem) from one dashboard significantly reduces "truck rolls" and support costs. Flexible Deployment Models: In 2026, it's rare to find a vendor that supports Hardware, Software (Private Cloud), and Hosted Cloud with the exact same feature set. It allows us to pivot based on the client’s budget or compliance needs. Modern AI Toolkit: The recent addition of AI Call Summaries and Sentiment Analysis in the P-Series has turned a "phone system" into a "business intelligence tool," making it a much easier upsell to management. Seamless Migration: Their 3CX-to-Yeastar migration tool actually works. It imports extensions, IVRs, and phone MAC addresses, turning a 2-day migration into a 2-hour task.
